ment lof the pull the forward end of the knife-carrying frame Edownwardly upon forward swinging movement of the handle 12, and toautomatically raise the forward end of said frame when the handle isswung rearwardly.

In operation, the knife-carrying frame E is swung upwardly andrearwardly by the handle 12, to thereby clear the base A; and permit thesteak or other meat to be readily placed on thev base. The frame E isthen swung forwardly and downwardly by the handle 12, and during thismovementthe rear end ofthe framewill swing about the arc traversed bythe pivotal connection between the Arear rod 16 of the frame and thebearing openings 18 of the lever arms 9, the front end of the frame willbe'pulled downwardly by the lever arms 8 and springs 22, the rear end ofthe frame will be moved rearwardly by the lever arms 9, and the frontend of the frame will be moved downwardly and rearwardly by reason ofthe rollers 19 engaging the slots 6 of the standards. 'Ihe downwardmoveframe is adjustably limited by the stop screw 13 whereby the meatmay be cut through to a more or less extent as may be desired. The frameis then raised, the meat turned' 90 degrees, and theV frame againlowered to form resultant cross cuts inthe meat.

Weclaim as our invention: f1. In a meat vtenderer,

secured Vthereon and having rearwardly and f downwardly extending camslots formed adjacent the forward ends thereof,`a knife-car- Y ryingframe disposed between the standards v,cutting knives and comprisingspace dside bars and front and rear transverse rods connecting the bars,

3. In a meat tenderer, the4 combination with a base, of a pair of spacedstandards secured thereon and having rearwardly and downwardly extendingcam slots formed adjacent the forward ends thereof, a lmife-carryingframe' disposed between the standards and'comprising spaced side barsand front and rear transverse rods connecting thebars,

the ends of the front rod projecting into the cam slots of thestandards, a plurality of cutting knives located betweenthe sidebars ofthe frame and connected to the frontand rear Vrods thereof,an operatingshaft'disposed in rear of said frame V endsV journaled in the standardsadjacent the rear ends lever arms fixed to the operating shaft andhaving pivotal connections with the rear transverse rod of the frame, anupwardly extending lever arm fixed to the operating shaft, and providedwith' a'laterally extending lug adjacent itsupper end, an upwardly andrearwardly extending arm, rigidlyv ,con-

carrying frame and having its upper Vend normally in contact with saidlug, a spring connecting the upwardly extending'v lever and the upwardlyand rearwardly extending arm for normallyfmaintaining contact with thelug. v

4. In a 'meat tenderer, the combination with a base, of a pair of spacedstandards secured thereon and having rearwardly and downwardly extendingcam slots formed adjacent the forward ends thereof, a knife-carryingframe disposed between the standards and comprising spacedside bars andfront and rear transverse rods connecting'the bars, the ends ofthe frontrod a plurality of cutting knives located betweenthe side bars of theframe and connected to the front and rear rods thereof, an operatingshaft disposed in rear of said ends journaled in the standards adjacentthe rear ends thereof, forwardly extending Vlever arms fixed totheoperating shaft and having pivotal yconnections with the rear transverserod of the frame, an operatinghandle fixed to one end ofthe operatingshaft, and an adjstable stop screw carried by the handle for cooperationwith the adjacent standard to limit he forward and downward movement ofthe handle. l

5. In a meat itenderer, the combination4 the sidefbars of the knifethelever in frame and having its 'and having its thereof, forwardlyextending projecting into the cam slots of the standards,

In testimony whereof, we have hereunto with a flat support, of a air ofspaced l standards secured thereto and) adjacent the forward end wlthdownwardly and rearwardly extending cam slots, a bell fra-nie andconnected to the front and rear u rods thereof, antifriction rollersjournaled on the ends of the front rod for engaging the side walls o fthe c am slots, each side bar with said lugs, an operating handle fixedto the projecting end of the operating shaft, a stop lug disposedbelowthe operating handle 'and extending laterally from the adjacentstandard, and a stop screw threadably engaged in the handle for engagingthe stop lug limit the downward and forward movement of the cuttingknives.
